Let me help you.
From our side there is no driver that can make the port show as COM port but I do would like you to check the developer’s community for a possible driver.
Please post your query here:
I have posted the question in the developers area, to no avail. I find it odd that Intel develops a motherboard with hardware functionality and dedicated pin headers to expose that functionality, and then does not provide the drivers to use that hardware under a common operating system with common applications.
A bit more info, I was able to extract the embedded drivers from the July driver bundle file and I can manually add those drivers. That works, I now have UART ports in my list of hardware. Unfortunately the driver does not show up under 'ports' and does not provide a COM port entry. Looks like Intel NUC is not going to suit my needs.
